Abstract: The present invention relates to a breast pump including a cylindrical housing encapsulated by an insulated thermal layer; the housing includes an outer wall and an open top in communication with an interior chamber. Superimposed on the open top is a removable pump assembly having a pair of outlet tubes extending therefrom. At a distal end of each tube is a conical suction cup for placing over a nursing mother's breast nipple. Any one of a plurality of varying sized auxiliary containers, such as a conventional baby bottle, can be placed within the interior chamber to receive and store breast milk extracted from the breasts.
